Section 5 - Troubleshooting

8. Can the DCS-5220 be connected to the network if it consists of only private IP addresses?

Yes, the Internet Camera can be connected to a LAN with private IP addresses.

9. Can the DCS-5220 be installed and work if a rewall exists on the network?

If a rewall exists on the network, port 80 needs to be opened for ordinary data communication. The DCS-5220

uses HTTP port and RTSP port to stream video data. These ports (or the ports you specify from the Advanced Tab

in the Conguration screen if you change the default ports) need to be opened in the rewall device. Please refer to

page 124 for more information.

10. Why am I unable to access the DCS-5220 from a Web browser?

If a router or rewall is used on the network, the correct ports for the DCS-5220 may not be congured on the

router or rewall. To correct the problem, you need to determine if the DCS-5220 is behind a router or rewall and

if the router or rewall is properly congured for the ports the DCS-5220 is using. Refer to page 124 for help in

opening the correct ports on a router or rewall for use with the DCS-5220.

Other possible problems might be due to the network cable. Try replacing your network cable. Test the network

interface of the product by connecting a local computer to the unit, utilizing a Ethernet crossover cable. If the

problem is not solved the Internet Camera might be faulty.

11. Why does the Internet Camera work locally but not externally?

This might be caused by network rewall protection. The rewall may need to have some settings changed in

order for the Internet Camera to be accessible outside your local LAN. Check with the Network Administrator for

your network.

Make sure that the Internet Camera isn’t conicting with any Web server you may have running on your network.

The default router setting might be a possible reason. Check that the conguration of the router settings allow the

Internet Camera to be accessed outside your local LAN. Please refer to page 124 for more information.
